Split System Air Conditioning

Split air conditioning systems are named because the system is split between the inside and outside of the house. The condenser is placed outside the house while the fan coil is installed inside. Heating and cooling works by removing warm air from inside the room, by the fan coil, which results in cold air recirculating the house.
